The 24th Amendment to the United States Constitution, ratified in 1964, was a significant milestone in Black history as it played a crucial role in the struggle for civil rights and voting rights for African Americans. The amendment prohibited the use of poll taxes in federal elections, which had been used in many Southern states as a way to disenfranchise Black voters.

Poll taxes were fees that voters were required to pay in order to cast their ballots, effectively preventing many African Americans and low-income individuals from voting. By abolishing the poll tax for federal elections, the 24th Amendment helped to ensure that all citizens, regardless of their financial means, could exercise their right to vote.

The elimination of the poll tax was a key victory in the broader civil rights movement, which sought to dismantle discriminatory practices that undermined African Americans' political and social rights. The 24th Amendment paved the way for further progress in the fight for voting rights, including the passage of the Civil Rights Act of 1964 and the Voting Rights Act of 1965, which aimed to end racial discrimination in voting practices across the United States.
